A fundamental fact about human minds is that they are never truly alone: all minds are steeped in situated interaction. That social interaction matters is recognized by any experimentalist who seeks to exclude its influence by studying individuals in isolation. On this view, interaction complicates cognition. Here, we explore the more radical stance that interaction co-constitutes cognition: that we benefit from looking beyond single minds toward cognition as a process involving interacting minds. All around the cognitive sciences, there are approaches (...) that put interaction center stage. Their diverse and pluralistic origins may obscure the fact that collectively, they harbor insights and methods that can respecify foundational assumptions and fuel novel interdisciplinary work. What might the cognitive sciences gain from stronger interactional foundations? This represents, we believe, one of the key questions for the future. Writing as a transdisciplinary collective assembled from across the classic cognitive science hexagon and beyond, we highlight the opportunity for a figure-ground reversal that puts interaction at the heart of cognition. The interactive stance is a way of seeing that deserves to be a key part of the conceptual toolkit of cognitive scientists. (shrink)

Much philosophical attention has been devoted to the truth predicates of natural language and their logic. However, lexical truth predicates are neither necessary nor sufficient for a truth-attribution to occur, which warrants closer attention to the grammar of truth attribution. A unified analysis of five constructions is offered here, in two of which the lexical truth predicate occurs (It's true that John left and That John left is true), while in the three remaining, it does not (John left; It seems (...) that John left; and It's that John left). This analysis is philosophically significant for four reasons. First, it explains why speakers of natural language find standard instances of Tarski-inspired equivalences (e.g. That John left is true iff John left) intuitively compelling. Second, it derives the widespread ‘deflationist’ intuition that truth has no substantive content. Third, insofar as the deflationist sees insights on truth as flowing from understanding our practice of truth attribution, it furthers the deflationist agenda through a new analysis of such attributions. Finally, it advances the philosophical project of the ‘naturalization’ of truth by reducing our understanding of truth to our competence in the grammar of truth, as an aspect of our biological endowment.

Traditional grammar and current theoretical approaches towards modelling grammatical knowledge ignore language in interaction: that is, words such as huh, eh, yup or yessssss. This groundbreaking book addresses this gap by providing the first in-depth overview of approaches towards interactional language across different frameworks and linguistic sub-disciplines. Based on the insights that emerge, a formal framework is developed to discover and compare language in interaction across different languages: the interactional spine hypothesis. Two case-studies are presented: confirmationals and response markers, both (...) of which show evidence for systematic grammatical knowledge. Assuming that language in interaction is regulated by grammatical knowledge sheds new light on old questions concerning the relation between language and thought and the relation between language and communication. It is essential reading for anyone interested in the relation between language, cognition and social interaction. (shrink)
